Hi Saikrishna,

Based on your description, there are serval reasons for this issue.

If you have installed AV softwares on Windows Server 2008, please try uninstalling it temperately and test whether this will make any difference.

Moreover, You could also try disabling TCP Chimney Offload, RSS, Receive Window Auto-Tuning Level on Windows Server 2008 one by one to see whether it makes any difference.
